The expression profiles of these transcripts at different develop- mental stages （from -96 to 48 h） revealed that the genes are expressed in an age-dependent manner. The transcripts of these genes continued to increase despite decapitation, and compared with normally developmental females, decapitation significantly inhibited their expression. Further experiments with a methoprene, a juvenile hormone （JH） analogue, challenge showed that JH was not a key inhibiting factor in the expression of these genes, and mating was found to significantly inhibit the expression of these marker genes.
